Internal biliary fistulas are considered a rare complication of biliary disease and even rarer of duodenal ulcers. They are an occasional finding during endoscopic retrograde cholangiography during the study of recurrent biliary disease. It is mainly related to complicated vesicular lithiasis. It can affect up to 2 % of all patients with biliary disease and is associated with a higher incidence of carcinoma in this system. The most common localization is between the gallbladder and the duodenum (cholecystoduodenal) in 72-80 % of cases. The choledocoduodenal type, related to the case to be reported, is the least frequent, which is found in 3-5% of the cases. A case is presented of a 44-year-old male patient, operated 26 years ago for perforated duodenal ulcer. In October 2015, the patient debuted with light icterus, choluria and pain to the right hypochondrium, which seemed to be toxic hepatitis, a clincal frame that relapsed in several occasions. During the study performed in his last crisis, a choledochoduodenal fistula was found and he was referred to our center for surgical treatment. Due to the infrequent case, it was decided to review the current literature and its presentation.
